Don't change a single character in this message ! This would invalidate the signature.

If you want to change the message, remove everything that is not your message (the special lines), change your message and sign it again.

Then you just have to send the message.

Decrypt a message and/or check its signature

gpg

If you are the addressee of a message, you will be able to decrypt it.
If the message is signed and you have the corresponding public key of the person, you will be able to check that the message really comes from this person.

Imagine you are in a windows where the message you received is displayed (browser, email program, text editor...):

Right-click on WinPT tray icon > "Current Window" > "Decrypt/Verify"

If the encrypted message is addressed to you, you will have to enter the passphrase which protects your secret key. Click "OK".

A window opens showing who signed this message and if the signature is good.
If you see "The signature is good", it means the message really comes from that person.

Otherwise, nothing proves the message is authentic. The message may have been be forged or tampered.

If the message was encrypted, it should appear decrypted on screen.

(If the message was encrypted and did no decrypt, it should be in the clipboard: Just paste the message in Notepad.)

Conclusion

Now you know the basic operations of WinPT/gpg.

You have all you need to securely communicate with anyone, and ensure of the identity of the authors of messages.
